Litigation

  • Our litigation team is able to advise on all aspects of IP litigation in the UK, as well as strategies for multi-jurisdictional disputes. As well as handling stand-alone contentious matters, our litigation team provides a base of knowledge and experience for the other attorneys in the firm to call on in advising their clients.

    Getting your rights protected is not always the end of the road. Occasionally competitors will start activities that you consider infringe those rights. Alternatively you may receive letters from your competitors indicating that they consider that you infringe their rights and threatening legal action.

    All our attorneys are happy to provide you with advice on how to deal with suspected infringements or with threatening letters received from a competitor. Many of these issues are resolved quickly following discussions between the two sides. However, for those issues where no resolution is possible litigation may result. Our litigation team is able to provide advice both on what needs to be done before an action is started in the courts, and once litigation has been started.

    In some cases we will recommend that you instruct a firm of solicitors to handle litigation, particularly where the case is likely to require significant resources. In such cases we can recommend appropriate firms to you, and can also continue to assist on specialist matters during the litigation. Several of our attorneys have considerable experience in such work.

    If you wish to contact us regarding a contentious issue, please address your query in the first instance to your usual Mewburn Ellis contact, or otherwise to Matthew Naylor (patents and designs) or Stephen Hodsdon (patents, trade marks and designs).
